Anticipatory Postural Adjustments During Gait Initiation in Stroke Patients
2019
Prior to gait initiation (GI), anticipatory postural adjustments (GI-APA) are activated in order to reorganize posture, favorably for gait. In healthy subjects, the center of pressure (CoP) is displaced backward during GI-APA, bilaterally by reducing soleus activities and activating the tibialis anterior (TA) muscles, and laterally in the direction of the leading leg, by activating hip abductors. In post-stroke hemiparetic patients, TA, soleus and hip abductor activities are impaired on the paretic side. Reduction in non-affected triceps surae activity can also be observed. These may result in a decreased ability to execute GI-APA and to generate propulsion forces during step execution. A s…
Corticospinal Tract Integrity and Long-Term Hand Function Prognosis in Patients With Stroke
2019
Background: The restoration of hand function is an important goal for patients with stroke. This study investigated the relationship between corticospinal tract (CST) integrity and the functional status of the hand in patients with stroke 6 months after onset and evaluated which of the following values would be useful for predicting hand function: fiber number (FN), fractional anisotropy (FA) at the mid-pons, and FA at the pontomedullary junction. Methods: The present retrospective cross-sectional observational study assessed 44 patients with stroke who were able to walk without using a walking aid or orthosis. The final hand function results were classified into three groups: no recovery (…
Multi-Sensorimotor Training Improves Proprioception and Balance in Subacute Stroke Patients: A Randomized Controlled Pilot Trial
2019
Introduction: The objective was to determine whether advanced rehabilitation therapy combined with conventional rehabilitation therapy consisting of sensorimotor exercises would be superior to usual treadmill training for proprioception variation and balance ability in subacute stroke patients. Methods: Thirty subjects (post-stroke time period: 3.96 ± 1.19 months) were randomly assigned to either a multi-sensorimotor training group (n = 19) or a treadmill training group (n = 18). Both groups first performed conventional physical therapy for 30 min, after which the multi-sensorimotor training group performed multi-sensorimotor training for 30 min, and the treadmill training group performed t…
Assessment of genetically modified sugar beet H7‐1 for renewal of authorisation under Regulation (EC) No 1829/2003 (application EFSA‐GMO‐RX‐006)

Efsa Panel On Genetically Modified Organisms (gmo)Scientific opinionRequestor: European Commission (DG SANTE)Question number: EFSA-Q-2017-00026; Following the submission of application EFSA-GMO-RX-006 under Regulation (EC) No 1829/2003 fromKWS SAAT SE and Monsanto Company, the Panel on Genetically Modified Organisms of the EuropeanFood Safety Authority (GMO Panel) was asked to deliver a scientific risk assessment on the datasubmitted in the context of the renewal of authorisation application for the herbicide-tolerantgenetically modified sugar beet H7-1. The data received in the context of this renewal applicationcontained a systematic search and evaluation of literature, updated bioinforma…
Group cohesion, needs satisfaction, and self-regulated learning: A one-year prospective study of elite youth soccer players' perceptions of their clu…
2018
Abstract Objectives With an overarching aim of investigating the importance of group perceptions on factors believed to underpin the quantity and quality of athletic practice, the purpose of the present study was to examine the relationship between perceptions of group cohesion and elite youth soccer players' basic psychological needs satisfaction and self-regulation over a one-year period. Design Prospective study design involving data collection at two time-points over a one-year period. Method A total of 332 elite youth soccer players selected at Norwegian regional U14 (N = 154) and U 13 (N = 178) levels completed questionnaires measuring perceptions of club-team cohesion, and individual…
A Grounded Theory of Elite Male Table Tennis Players’ Activity during Matches
2006
International audience; This article describes the main features of a collaborative project involving researchers, coaches, and elite table tennis players. The project was carried out between 1997 and 2002 with funding from the French Ministry of Youth and Sports, in response to a request by French Table Tennis Team coaches to improve the training of table tennis players. Matches were videotaped during international meets and followed by interviews during which the players described and commented on their activity as they viewed the tapes. A grounded theory of players' activity emerged from the data collected and the ensuing theoretical issues that were raised. The findings on table tennis …

A meta-study of athletic identity research in sport psychology: Current status and future directions
2015
ABSTRACTThe aim of this meta-study is to provide a critical synthesis of qualitative research on athletic identity in sport psychology. A total of 108 empirical studies were identified, including 63 quantitative studies, 40 qualitative studies, and five mixed methods studies. Qualitative and mixed methods studies were reviewed with the meta-study method, which involves a meta-analysis in terms of theoretical perspectives, methodologies, and findings. In our discussion we focus on evaluating and critiquing the current status of qualitative research on athletic identity and outlining recommendations for improving methodological rigor. It is concluded that both quantitative and qualitative stu…
Una revisión de las bases neurobiológicas de la dislexia en población adulta
2017
Resumen: Introducción: La dislexia en la edad adulta afecta a alrededor del 4% de la población. Sin embargo, la investigación acerca de los sustratos neurobiológicos de la dislexia en población adulta es relativamente escasa en comparación con la realizada en niños. Objetivo: El presente estudio ofrece una revisión de las bases neurobiológicas de la dislexia en población adulta. Desarrollo: A partir de una búsqueda bibliográfica en la base de datos del Psychological Abstracts: PsycINFO, se identificaron 11 trabajos sobre las bases genéticas, 9 estudios que emplearon técnicas de neuroimagen estructural, 13 artículos que emplearon técnicas neurofuncionales, y 24, neurofisiológicas. Los result…
